I have a document with a date field. The document is in Calibri but every time I open the file (many times a day) the date has chamged to Courier, English, Writer
Windows 7, English

Got it. Tools, Options, LibreOffice Writer, Basic fonts and change them all to Calibri. Maybe not perfect but that’s the only font I use.

I have the same problem, but in Calc. Every time when I open a saved spreadsheet, the font type change to Courier New … Any idea to solve that please ?

Many thanks.
